[issue15223] datetime instances lack __module__ attribute

Amaury Forgeot d'Arc added the comment: In PyPy, datetime.py is a pure Python module (similar to the one in 3.x, but without the _datetime acceleration module). So comparison with CPython is not relevant here. In CPython, __module__ is not an attribute of the type, but a property: it is def
